IMPROVEMENT IN TYPOGRAPHIC MACHINES.

To .all tohonra't that I, THOMAS HALL, of'Ber- -State of New J ersey,- have invented a new and useful, Machine for Writing with Type or Printing on `Paper or and I do hereby declare that the following isa full, clear, and exact description of the construction and operation of the sam'e, reference being had to the annexed drawings making a part of this specification, in which- Figure 1 -is a perspective view'otthe machine, showing its workingparts. Figs. 2 and 3 are side and front elevations of the table and connections; and Fig. 4, an end view of stop-motion, as described in following explanation.

A A represent the'frame of the machine, to which ali the working parts are attached. B B is a plate extending from side to side of the frame, to which are fixed the type and connections for operating them. C C are hangers or supports for type-levers E e E e, which are acted upon by levers D D through rods` g g. The type F F are fixed on levers c e, so that they cap be rotated on their round. shanks to adjust them so that they will strikeparallel with eachother. R is a ring or circular stop' orcushion,- provided to stop the type-lever i from descending too far, or sinking into material being printed on. This by rods V Vaud nuts on plate B. The typelevers 'e e are also adjustable by set-screw e. (Shown in Fig. 2.) The levers D D, which opcrate the type, are provided with finger-pieces d d, which project through the case andform a key-board, by which the machine is operated upon. 2 vis a vhollow shaft, adjusted with a slot, so that the pieces 1 1, which are attached to levers D D, can enter the slot, any one of which entering tip the shaft 2, so that no ring is adjustable I position,

other spring on c to operate slides freely from left to right, but which bites on rod M when it moves from right to left, and carries the frame N with it.

The movement of the frame N takes place as the action of each type and the distance moved corresponds with the width of the type use The adjustment is lmade either by the various lengths of levers I I I I, or by the rods z' i being made of di'erent lengths, so that levers D,D D D shall cause rods i to move but a part of the movement of levers D D D D.

K is a nut on the lever J, by turning which will cause lever J to be lengthened or shortened, thereby giving facility for varying the space between each letter printed uniformly. Q is a lever, connecting shaft t, lever s', rod r, lever q, and rod p to bar X, (shown in Figs. 2 and 3,) the objectoi' which is to move the frame N, carrying table P, to the right or left. When moved to the right it acts on 'clutch n and raises it, enabling it to slide freely on rod M. The table P is placed on frame N, and slides freely backward and forward by the action of rail T, to which it is attached by clasp U. lRail T is fixed at each end to rods T T', on which it slides, and is moved parallel by rods fw 1c and levers W W on shaft Y. Shaft Y is moved by rod y, connecting with knob Z, by which the operator can move table to any and retain it there by a catch at lower end of knob IZ, which catches into notches in platez. V is a plate, which moves parallel with lower edge of plate z, in order to release knob Z fromv notch in e, and isopen ated by levers a c, rod' b, lever c,hollo'w shaft c', and catch j'. Spring S holds catch f iu'place until frame N moves up to it and pushes, by rod m, thev spring S from catch f, and thereby allowing on lever c and push can enter nntilthe first is withdrawrnas shown rod b, the end oi" which, b', coming in erm- 4.
